Title: Flavor Dependence of T-odd PDFs

Abstract

The flavor dependence of the naive time reversal odd ("T-odd'') parton distributions for $u$- and $d$-quarks are explored in the spectator model. The flavor dependence of $$h_{1}^{\perp}$$ is of significance for the analysis of the azimuthal $$\cos(2\phi)$$ asymmetries in unpolarized SIDIS and DY-processes, as well as for the overall physical understanding of the distribution of transversely polarized quarks in unpolarized nucleons. As a by-product of the formalism, we calculate the chiral-odd but ``T-even'' function $$h_{1L}^{\perp}$$ which enables us to present a prediction for the single spin asymmetry $$A_{UL}^{\sin(2\phi)}$$ for a longitudinally polarized target in SIDIS.

  • It has been suggested that under certain approximations the Sivers effect can be described in terms of factorization of final state interactions and a spatial distortion of impact parameter space parton distribution; that is a convolution of the so-called lensing function and the impact parameter GPD E. In this approach the lensing function is calculated in a non-perturbative eikonal model. This enables a comparison between the a priori distinct Sivers function and the GPD E which goes beyond the discussion of overall signs.

  • Nonleptonic weak decays of strange hadrons are complicated by the interplay of weak and strong interactions. Models based either on symmetry properties or on the selection of certain types of diagrams are both open to criticism. The symmetries used are all broken in strong interactions, and the selection of some diagrams and neglect of others is never seriously justified. Furthermore, the number of related decays of strange hadrons is small, so that experimental data are insufficient for singificant tests of phenomenological models with a few free parameters. The discovery of charmed particles with many open channels for nonleptonic decays hasmore » provided a new impetus for a theoretical understanding of these processes. The GIM current provides a well defined weak hamiltonian, which can justifiably be used to first order. The QCD approach to strong interactions gives flavor-indpendent couplings and flavor symmetry broken only by quark masses. In a model with n generations of quarks and 2n flavors, a flavor symmetry group SU(2n) can be defined which is broken only by H/sub weak/ and the quark masses.Here again, the same two approaches by symmetry and dynamics have been used. But both types of treatment tend to consider only the symmetry properties or dominant diagrams of the weak interaction, including some subtle effects, while overlooking rather obvious effects of strong interactions.« less

  • The measurement of exclusive reactions at large momentum transfers provides an important testing ground for models of hard quark-quark scattering. We have measured cross sections or set upper limits for 12 meson-bryon (..pi../sup +-/p ..-->.. p..pi../sup +-/, p/rho//sup +-/, ..pi../sup +/..delta../sup +-/, K/sup +/..sigma../sup +-/, ..pi../sup /minus//p ..-->.. ..lambda../sup 0//..sigma../sup 0/K/sup 0/, K/sup +-/p ..-->.. pK/sup +-/) and 2 baryon-baryon (p/sup +-/p ..-->.. pp/sup /plus minus/) reactions near 90/degree/ C.M. by studying the flavor-dependence of these 2 exclusive reactions at t = -9(GeV/c)/sup 2/, we have been able to demonstrate in a perturbative QCD picture that the quark-interchange mechanism ismore » dominant over gluon exchange and quark-antiquark annihilation. We will also present preliminary results on many of these reactions at t = -5(GeV/c)/sup 2/ with better resolution and statistical precision. 145 refs., 3 figs.« less
